Taylor Swift Songs About Joe Alwyn See Big Increases in Streams Post-Breakup

Taylor Swift's music is seeing a huge spike amid news of her breakup with Joe Alwyn -- but the interest is focused on specific tracks, with a specific muse in mind ... take a guess.

The numbers are in -- as aggregated by TS stan SpotifySwiftie -- and it looks like several songs from TayTay's past few albums have seen massive streaming increases in the past 48 hours ... but, perhaps unsurprisingly, they're all tunes rumored to be about her now-ex.

The songs in question span her last 5 projects -- which cover the time frame that she's been with Joe -- and they range in percentages ... from as low a boost as 23% to as high as 106%, and everything in between. There are 11 tracks we're talking about here, BTW.

'King of My Heart' from her album 'Reputation' and 'happiness' from 'evermore,' for example touch the low end of the totem pole (at 23% increases each) ... whereas other songs like 'Sweet Nothing' ('Midnights') and 'the 1' ('folkore') are at 30% and 39%, respectively.

Other songs, however, have even more plays ... cuts like 'New Year's Day' ('Reputation'), 'peace' ('folklore') and 'Daylight' ('Lover') have jumped 40%/48%/58% in streaming stats.

The song of hers that has the largest upswing is 'Cornelia Street' ('Lover') at 106%. Some of the telltale lyrics in there that allude to Joe include this line ... "And I hope I never lose you, hope it never ends // I'd never walk Cornelia Street again // That's the kind of heartbreak time could never mend." It's been reported they shared a home on this NYC street, for real.

Funny enough ... there's actually viral video of New York-based Swifties leaving flowers at the rumored house they used to live in -- mourning the fact that Joe and Taylor are dunzo.
